“…Although the non-linearity is strongly evidenced, this numerical analysis is able to evaluate the ring stiffness from the maximum slope of the first trend, as defined in Equation (1). Then with a simple geometrically linear model it is possible to find out the ring stiffness of the prototypes.…”

“…Particularly these objects exploit dearly the properties of high rigidity and reduction of the vibration of the composite materials to improve their performances, and to reduce weights, winning the challenge with traditional products as wood, steel and aluminum [1]. Due to the limited availability of design criteria for composite structures, the product characteristics, in terms of mechanical performances, are still left to the experience of the manufacturers, and their reliability is tested on board ship [2].…”

Composite materials are widely employed in sailing sports, a possible application is for the mast pole or other sail poles. In the paper the attention is focused on the spinnaker poles mechanical performances; in particular the focus is on axial and ring compressive properties of three different carbon fibre/epoxy resin spinnaker poles, to investigate both the diameter and stacking sequence effect on the mechanical performance of the structure. Starting from the stacking sequence used in the production of a particular spinnaker pole, the effect of a lamina at 0-in the middle of wall thickness is investigated with the purpose to obtain a more stiff structure. Moreover to test the proposed stacking sequence on different size products, a prototype with lower diameter is realized. To properly evaluate axial and ring stiffness, axial compression test and ring stiffness one are performed. Then a numerical model is developed to support the design of the finished product: A simple and versatile numerical analysis (FEA with software ANSYS), by simulating ring stiffness and pull-direction compression tests, is carried out in elastic regime. Such model should be suitable for designing and/or verifying the mechanical Appl Compos Mater (2006) 13: 217-235 performance of pole structures, even though differing from those above described, for materials, geometry and stacking sequence.

“…These systematic errors can be removed by using an analytical procedure of error minimization similar to the one developed by Arbocz and Babcock [28], and later used by other authors, considering cylindrical structures [29]. The basic idea of the procedure is to find the plane surface that better fits the measured points in the sense of the minimum square error.…”

“…The buckling analysis of circular FGM plates under radial compressive load is given by Najafizadeh and Eslami [13]. There are several publications on buckling of imperfect shells under mechanical or thermal loading, such as studies of Pandey and Sherboune [14], Palassopoulos [15], Kasagi and Sridharan [16], Shen [17], Eslami and Shahsiah [18,19], Tsouvalis et al [20], Patreli and Tsouvalis [21], Wunderlich and Albertin [22], and Mirzavand et al [23]. Shahsiah and Eslami [24,25] studied the thermal buckling of functionally graded cylindrical shells under several types of loadings based on the Donnell and the improved Donnell equations.…”

Thermal instability of functionally graded deep spherical shell

2010

View full text Add to dashboard Cite

Thermal instability of deep spherical shells made of functionally graded material (FGM) is studied in this paper. The governing equations are based on the first-order theory of shells and the Sanders nonlinear kinematics equations. It is assumed that the mechanical properties are linear functions of thickness coordinate. The constituent material of the functionally graded shell is assumed to be a mixture of ceramic and metal. The analytical solutions are obtained for three types of thermal loadings including the uniform temperature rise (UTR), the linear radial temperature (LRT), and the nonlinear radial temperature (NRT). Results are validated with the known data in literature.
